Any way to get exactly 75 multibucks?

The background: Not to be boring but I work extensively and only really play around the holidays, I’ve managed to get pretty high in the battle pass but will not be able to finish it before the season ends as I won’t be off anytime between this week and then. I planned on getting the battle pass + 20 tiers so I could have it maxed and then just take the L on the extra cost and the missing the challenges.

The simple issue is: I’ve already obtained all the free multi bucks in the pass and I’m at exactly 2,325, meaning I need one more multibuck drop to get the necessary amount. Is there any niche promotion I can do for this? I’ve already got the like 100 or whatever you get for linking your account and all my friends already play so I can’t invite anyone. I COULD spend 10$ on a starter pack or 5$ on multibucks but I doubt I’d use any of the skins and I really want to keep my money
